The invention relates to trays we: of paper, paper board or likeflexible moteriel, particularly adapted for holding bread and simileredible products. The object of the invention is to provide e simple traywhich moy be mennfectured etlow cost, and which may be shipped flat in acollapsed condition, and which, when orrived st its destination, may Mreadily set up to receive the desired article, such as e loaf of breed.

According to the preferred embodiment of my invention, the trey may beformed from a single blenk, which may be readily formed into a box ortrey adapted to be shipped list, end wbicli may be set up by merelypushing inwardly on the end wells,

thereby opening up the side wells, whereupon locking reps, preferablyformed integral with the end walls, ere folded inwardly over the endwalls, thereby holding the box in' assembled or set up position. Theloclrin flaps are readily opereted by a simple folding oration, andfirmly hold the box in assemled position without the necessity forfitting tabs into slots, or the employment of complicated fasteningmeans, end may be as resdily opened 11 to again ermit collapsing of thetrey. lhe collapsing operation is mode possible by dingo-eel scoring ofthe end ilaps. ".lhe locking flops, when inlolded, brece the end flopsto bending along diegonel lines, but :93 the locking ilops are openedup, bracin efiect is removed end the box may then be collapsed elong thelines of weakness. t llhile according to the herein disclosed embodimentof the invention, the ends oi": the tray are diagonally scored and theloosing dens applied thereto, it obvious that s similer errengementmight be applied to the sides oi the trey. Accordingly, in the presentspecification it will be understood thet the terms ends end sides mey beinterchanged one for the other, es referring to opposite wells of thetrey.

The invention will be more readily understood by reference to theaccompanying drawing and the following detailed description Isettinforth an illustrative embodlment, it being understood that the'detallsmay be varied without departing from the spirit of the invention,

In the drawing, 7 Fig. l is o perspective View of the trey showing onelooking flap folded in place to hold the tray in assembled position andshipped e trey mey be formed from paper, paper boord, or other suitableflexible mote rial, end is preferably manufactured from a single blankwhich may be cut away in one stamping operation and suitably mored toprovide him ed flaps by means of which the blank may be assembled intothe form of a tray. The blank is shown i'ragmentarily in Fig. 2 andsince both ends of the troy ere alike, one end only is shown in thefigure.

The blank comprises a bottom portion 10 having sides 11 hinged theretoalon fiexi ble lines l2. Ends 13 tire hinged to t e bottom portion elongflexible lines M, these ends being provided with side extensions ortleps 15, which are adopted to be folded inwardly along lines it endposted to the sides ll when the box is assembled. The flaps 15 arepreferably separated Lironi the sides ll by sniteble cut-sway portionsll, herein shown as stroight at the edges of the sides ll end es fieringat the edges of the flaps 15. The purpose or" the out-sway portions isto facilitate folding and essembling of the box. Extending beyond theends 13 ere locking dope 18, preferably of the some till Mill

ill

inner ends of the slits diagonal score lines 21 extend outwardly tooints 24, where the score lines 12 and 14 m. The purpose of the diagonalslits 20 and score lines 21 is to facilitate collapsing of the tray, aswill be ap arent hereinaiter.

To form t e blank into a tray or box, the sides 11 are folded upwardlyalon the score lines 12, the ends 18 are folds upwardly along the linesid and s 15 are folded inwardly eionr lines 13. the he s 15 are thenglued to t e sides 11, as clear y indicated in m 1.

The box may be collapsed for shipment in the form shown in Fi 8. Thecells sing is accomplished by pressing the ends 1 outwardly, causin thetriangular port ons 22 thereof to fo inwardly alon diagonal lines 21,the triangular rtions 'n sepa! rated from the remain er of the en flapsalon the slits 20. Folding the ends 18 outwar y draws the sides 11inwardly by reason of the connection between the two through the luedflaps-15. The locking fla s 18 may either folded outwardly as in icatedat the rightin Fig. 3, or fo ded over the ends 13 mclndin the trian larportions 22, as indicated at t e left in Eng. 8.

Obviously the containers may be shipped in large quantities and occupy aminimum of space when collapsed in the manner shown in Fi 3. When thetrays have arrived at their destination they may be assembled for use bymerely pressing upwardly and inwardly on the end walls 18, forcing theside walls 11 outwardly. The tra maythen be locked in assembled positiony folding the flaps 18 inwardly so as to overlap the ends 13, coveringthe diagonal slits 20 and score line 21, thus preventing collapsingalong these weakened lines. It will be noted that the locking flap 18extends the full length and width of the end 13, so that a reinforcementalong its entire area is provided. The

fla s 18 fit in position, and due to the added th ckness caused by theglued fia s 15, a sli ht outward pressure is exerts on the sid es of thebox. Thus when once the flaps 18 have been folded into locking position,there is no tendency for them to again fly open, althou h they may bereadily opened manually. onse uently no tabs and slots are required inor er to retain the parts in assembled relation. A loaf of bread orother like article may now be readily inserted within the tray. I t

The locking flaps 18 constitute one of the important features of theinvention. They are preferably of such dimensions as to frictionallyengage both the sides and bottom of the container, when infolded inlockin osition. This frictional en agement is en cient to retain theflaps in e locking position and to maintain the container upright untilthe locking flaps are manually released.

The frictional engagement with the side walls of the container isincreased by the added thickness of the glued ilaps 15.

While in the above described embodiment of the invention the diagonalscore lines are provided in the ends 13 and the locking ape are providedas extensions thereof, it

is obvious that a similar arran ement could' side walls, diagonal scorelines extending from the ends of the lines of juncture beitweenthebottom and ends partially across the end walls, and diagonal slitsextending from the ends of the score lines outwardly to the edges of theend walls, whereby the tray may be collapsed along the diagonal scorelines by pressing outwardly on the end flaps, and means for locking thetray in upright position comprising locking flaps hmgedly connected tothe end walls and of equal length and width with the end walls, Saidlocking flaps when infolded completely overlapping the scored andslitted ortions of the end walls and serving to rein orce the same, toprevent colla wing and at the same time preventing infol ing of the sidewalls.
